【摘要】：随着人们物质生活水平的提高，景观桥作为现代都市的产物，越来越被人们所重视。桥梁建设己不纯粹以满足通行功能为目的，生态环境、人文文化及美学景观融入桥型的建设之中变得很是重要。一个地区，桥梁的建成与周边的环境是一个有机的整体。本文通过对景观桥梁的研究，结合湖南科技大学的人文环境、自然环境对湖南科技大学月湖景观桥进行景观设计以及结构计算，选择出最为适合的桥型，使之成为湖南科技大学具有标志性的安全可靠的建筑，从而为湖南科技大学核心区的景观建设增添亮点。针对上述问题本论文展开以下工作： ①本文的景观桥设计是在参考大量文献前提下进行的，明确了设计景观桥梁所涉及的研究方法和研究内容。对景观桥的研究背景、研究状况以及研究意义做了简要的概括。为湖南科技大学月湖景观桥设计提供了理论依据。 ②通过应用景观桥梁的设计规则，对不同桥型的美学性能进行分析、比较得出不同地区、不同人文环境以及不同地理环境应适应何种桥型。再结合湖南科技大学月湖桥所处的地域，对其人文环境、地理环境进行分析提出两个适合的方案。并对两方案从美学、造价以及施工技艺进行比较，选出与周边的环境最为融合，，最为适应的桥梁方案。 ③利用传统的手算方法对湖南科技大学月湖景观桥进行计算。计算内容包括主拱圈截面几何要素计算、拱轴系数的确定和拱圈截面强度、拱圈整体“强度—稳定”以及拱脚截面直接抗剪的验算。运用Midas/Civil桥梁软件对湖南科技大学月湖景观桥施工过程进行模拟，确定湖南科技大学月湖景观桥施工过程中所需的立模标高、预拱度以及各施工阶段的张拉预应力值，为湖南科技大学月湖景观桥的施工提供依据。
[Abstract]:With the improvement of people's material living standard, landscape bridge, as a product of modern city, is paid more and more attention.The purpose of bridge construction is not purely to satisfy the traffic function. The ecological environment, humanistic culture and aesthetic landscape have become very important in the bridge construction.In an area, the bridge is built with the surrounding environment is an organic whole.Through the study of the landscape bridge, the landscape design and structure calculation of the Yuehu Lake landscape bridge of Hunan University of Science and Technology, combined with the humanistic environment of Hunan University of Science and Technology, the most suitable bridge type is selected.It has become the iconic safe and reliable building of Hunan University of Science and Technology, thus adding a bright spot to the landscape construction of the core area of Hunan University of Science and Technology.In view of the above problems, this paper carries out the following work:1. The design of the landscape bridge in this paper is carried out under the premise of a large number of references, and the research methods and contents involved in the design of the landscape bridge are clarified.The research background, research status and significance of landscape bridge are briefly summarized.It provides a theoretical basis for the design of the landscape bridge of Yuehu Lake in Hunan University of Science and Technology.(2) by applying the design rules of landscape bridges, the aesthetic performance of different bridge types is analyzed, and the different regions, different cultural environments and different geographical environments are compared.Combined with the region of Yuehu Bridge of Hunan University of Science and Technology, two suitable schemes are put forward by analyzing the humanistic environment and geographical environment of Yuehu Bridge of Hunan University of Science and Technology.The two schemes are compared in terms of aesthetics, cost and construction skills, and the bridge scheme which is most integrated with the surrounding environment and most suitable for the bridge is selected.The traditional manual calculation method is used to calculate the landscape bridge of Yuehu Lake in Hunan University of Science and Technology.The calculation includes the calculation of geometric elements of the section of the main arch ring, the determination of the coefficient of the arch axis and the strength of the section of the arch ring, the overall "strength-stability" of the arch ring and the checking calculation of the direct shear resistance of the section of the arch foot.The construction process of Yuehu Lake landscape bridge in Hunan University of Science and Technology is simulated by using Midas/Civil bridge software, and the elevation of vertical formwork, pre-arch degree and tensioning prestress value in construction process of Yuehu Lake landscape bridge in Hunan University of Science and Technology are determined.It provides the basis for the construction of Yuehu landscape bridge in Hunan University of Science and Technology.
